Slim Error 0032

Apologies if this is wrong section, but having looked for a long time I've found little help.. Console was bought off eBay knowing it had the red dot, but didn't say anything else - it had already been opened so maybe tampered with.

So far it seems it's either faulty temp sensor or last owner tried to solder something up and removed a pad but I don't see any areas where soldering has caused any issues

Have cleaned cpu/heatsink and used new paste but still same, although compared to my other slim, the heatsink seem to move a little more.

Annoying problem seems related to a bad nand flash or something along those lines - What's the cheapest way I could flash the nand back to original/retail?

According to another forum, depending on how long it takes for the red light to appear, it could be several problems, did 3 timings: once was 22sec & other 2 27sec, which points towards need reflow/reball etc.

..I was skeptical about buying a faulty console, and my worst fears came true. I'm in UK, and people who do such repairs probably aren't available in my area or would be too expensive.
